Clark Begins First Phase of Hobby Airport Expansion Project

June 26, 2006

HOUSTON – Clark Construction Group, LLC has started the first phase of the William P. Hobby International Airport expansion project for the Houston Airport System. Phase 1 consists of three stages: a five-gate expansion of the Central Concourse; demolition of Concourse C and the West Apron; and demolition and abatement of Concourse A.

Hobby Airport, which has been in operation for over 60 years, served more than 8 million passengers last year. The Central Concourse will remain open during the project.

Designed by Lockwood, Andrews & Newnam, Inc., the five-gate expansion includes the construction of two main levels containing airport operation offices, an employee rest area, passenger holding rooms and concessions. The new space will add 12,000 square feet for airline tenants to the Central Concourse. Exterior walls on the lower level consist of masonry with punched windows. The upper floor is composed of a glazed curtain wall and metal panel facade topped with a high, curved standing seam roof. Demolition stages include hazardous materials abatement and approximately 325,000 square feet of apron demolition and replacement.

Phase 1 is scheduled to be completed in October 2008.

Additional members of the project team include Gowan, Inc., mechanical, plumbing and HVAC; Fisk Corporation, electric and communications; Rago Concrete, concrete; and Patriot Erectors, Inc., steel.

The Houston Airport System was named “Airport of the Year” for 2005 by the Federal Aviation Administration, Texas Airports Development Office, in part for its capital improvement program.
